Title	24-Hour Report Involving an Unplanned Contamination Event
Event Description	{{#Wiki_filter:An unplanned contamination event occurred on February 16th, 2009. This is a reportable event in accordance with 10CFR40.60 paragraph (1) based on an unplanned event that results in additional radiological controls being required for more than 24 hours. The 24 hour period ended at 1030 on February 17th, 2009. The additional controls imposed was wearing a half-face respirator in the basement of the Feed Materials Building. The Feed Materials Building converts uranium ore concentrates into uranium hexafluoride. Air samples from the basement were analyzed and the airborne radioactivity average was approximately 8.27 e-11 �Ci/ml. The airborne radioactivity exceeded the MTW action level of 30% of a DAC (5.0 e-11 �Ci/ml). One DAC is 1.7e-10. Uranium Tetrafluoride (green salt) was the material that was airborne in the basement. An elevator that is used to transport green salt to different levels of the Feed Materials Building was leaking around an inspection cover which caused the airborne radioactive material. The licensee attributes the contamination to a failed gasket. The airborne contamination was discovered during routine air sampling which is performed daily. There is no plan to perform personnel testing for uptake or ingestion at this time. }}
